Patent number: 6645562Abstract: A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.Type: GrantFiled: June 27, 2002Date of Patent: November 11, 2003Inventors: Gary David Greenblatt, Ward Thomas Brown, Michael Damian Bowe, Richard Foster Merritt, Ronald Scott Beckley, Barry Clifford Lange, Robert Wilczynski, David William Whitman, Martha Harbaugh Wolfersberger

Patent number: 6566549Abstract: A continuous process for oligomers which do not contain, as polymerized units, carboxylic acid-containing monomers and their salts, including the steps of: (1) forming a reaction mixture, substantially free of carboxylic acid-containing monomers and their salts, containing: (i) 0.5 to 99.95% by weight of the reaction mixture of at least one ethylenically unsaturated monomer; and (ii) 0.05 to 25% by weight, based on the weight of the ethylenically unsaturated monomer, of at least one free-radical initiator; and (2) continuously passing the reaction mixture through a heated zone wherein the reaction mixture is maintained at a temperature of at least 150° C. and a pressure of at least 30 bars for from 0.1 seconds to 4 minutes to form terminally-unsaturated oligomers. In addition, processes for forming oligomers of vinyl acetate and oligomers of vinyl alcohol are disclosed. Mixtures of fully saturated and terminally unsaturated oligomers are also disclosed.Type: GrantFiled: December 15, 1998Date of Patent: May 20, 2003Assignee: Rohm and Haas CompanyInventors: Gary David Greenblatt, Barry Clifford Lange, Michael Damian Bowe, Richard Foster Merritt, Robert Wilczynski, Gary Robert Larson, Lori Marie Petrovich, David William Whitman
